Owing to the trend of the canyon, and the lateness of the season, the sun now passed early from sight, the walls throwing the bottom of the gorge into deep shadow with a wintry chill that was quickly perceptible to us in our wet clothing.

The result was that our teeth chattered in spite of all we could do to stop the uncomfortable performance, and our lips turned blue.

To be soaked all day long near the end of September, in our climate, is not an agreeable condition.

Though less than seven miles was made this day we were forced to stop when the shadow fell and make a camp at the first opportunity.

It was only half-past three o'clock, but it had been sunset to us for half an hour.
